   system vimrc file: "$VIM/sysinit.vim"
  fall-back for $VIM: "/usr/local/share/nvim"

Steps to reproduce

1. open a file that has too many lines to fit into view nvim long-file.ext
2. try to use Ctrl+e to scroll downwards
3. nvim behaves as if you only pressed e and moves the cursor to the end of the next word

The same thing happens for Ctrl+y, Ctrl+u, and Ctrl+d

Expected Behavior

The aforementioned key combinations should:

• Ctrl+e scroll down one line
• Ctrl+y scroll up one line
• Ctrl+d scroll down half a page
• Ctrl+u scroll up half a page
• Ctrl+f scroll down a full page
• Ctrl+b scroll up a full page

Actual Behavior

The control key is "swallowed" and thereby:

• Ctrl+e puts the cursor to the end of the next word
• Ctrl+y does nothing
• Ctrl+d awaits a motion to delete something (hit twice to delete current line)
• Ctrl+u reverts the last change
• Ctrl+f awaits a character to jump forward in the current line
• Ctrl+b puts the cursor back one word

Additional notes

I mapped Ctrl+z to open fzf using zoxide. This works when the shell is active but not in neovim, either (separate config that maps the same keys). But these are custom keybinds that would require more effort to reproduce.
